Personalized Spatial Audio

Posted on by

I developed an appreciation for good audio headphones during my time at KBOA back in the ’70s. Not so much for the music as much as wanting/needing to hear my voice as the listener was hearing it. Too close to the microphone? Too far away? Popping my “P’s?” I’ve purchased a lot of headphones over the years, always searching for the perfect set.

I used Apple’s wired earbuds during the iPod days and thought the music sounded fine. I never purchased another set of “cans.” I purchased my first set of Apple AirPods in 2016 and have been using them ever since. They fit my ears perfectly. So well, in fact, that I forget I have them in. Unfortunately, that means I don’t notice if one falls out which happened last week. The Find My app on my phone told me where I last had the AirPod but I never found it.

When I got my new AirPods my buddy George asked if i had configured them to take advantage of Personalized Spatial Audio. I vaguely recalled reading about this feature but don’t think I ever used it. As good as I thought the AirPods were before, this bit of tech magic was impressive.

(Perplexity) It uses the TrueDepth camera on newer iPhones to scan your face and ears. This captures data about the geometry and contours of your head and ear position. This personalized profile is then used to optimize how spatial audio is rendered through your AirPods or Beats headphones. It adjusts the sound to account for your ear shape and head size, providing a more immersive 3D audio experience tailored specifically to your anatomy.

Songs I’ve listened to a thousand times sound fresh and new. So, yeah, I’ve become one of those people walking around with tiny white things in my ears. More and more I’m using Siri to schedule reminders, send messages, check the weather, jot down a note… you get the idea. My phone stays in my bag more these days and when at home, I leave it on the table and interact via AirPods (as long as phone and pods are on same wifi network.

This will get even more interesting this fall when I take the Apple Watch (with cellular) plunge.

DJI Osmo Pocket 3

I purchased this camera back in January but a busted arm and cold weather prevented me from plunging in as I usually do with a new toy. Additionally, I found myself overwhelmed by the number of features and settings. All excellent features, but there are so many of them. I couldn’t find a place to start. So yesterday I turned the camera on and headed into the woods, paying to attention to settings. The video below was shot at 1080/30fps. I’ve reset to 4K/60fps for the next shoot. Watch this space. (PS: A YouTube search will tell you all you might want to know about this little gadget.)

Drone view of corn harvest

My buddy George has been flying drones —and using them to record video— pretty much since drones have been available for the consumer market. He has become quite proficient.

The video below –the work of Jack Dodson, a friend and client– is a fascinating look at the corn harvest (from combine to truck) on the Steck farm in the Missouri River Bottom near Jefferson City. The video was captured with the DJI Mavic 3 Pro Cine.

Audigo Microphone

Posted on by

I’ve been using the Audix USB 12 microphone to record the audio for videos for a long time. Ten years? Sounds good but keeps me tethered to my MacBook which hasn’t been an issue for most of my stuff. But, occasionally, I’ve thought it would be fun to put the video camera (laptop or iPhone) further away. But then the audio suffers.

The first video below is a demo of the Audigo Microphone and app. The short video below that is my attempt to show the difference audio quality. Eager to try this out with a new uke song.

UPDATE: Sample (:50) off video recorded from across the room with audio from the Audigo mic.

Flickr Batch Organizer

Posted on by

Flickr launched in February, 2004. I created an account and started uploading photos in March, 2005. So I guess I’m a long-time user. My primary photo repository is the Photos app on my MacBook (mirrored in my iCloud account): 2,449 photos. I make some effort to only save “keepers.” Flickr is where I post photos I’d like to share with the world. All under Creative Commons license for unrestricted use. I have about 2,500 photos in my photostream organized into albums and collections.

This 12 minute video (I know, too long) is a very cursory explanation of how I use Flickr’s Batch Organizer to manage photos.
